LOOM 'FoR CROSS-WEAVING.

SPECIFICATION forming part of Letters Application filed February 19,1887. Serial No. 228,167.

To all whom it may concern.-

Be it known that I, CHARLES A. LITTLE- FIELD, a citizen of the UnitedStates, residing at Fall River, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inLooms for Oross-WVeaving; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of my invention is to provide by simple means for theproduction of a great variety of patterns in cross-woven fabrics.

My invention consists in theimproved construction of devices hereinafterdescribed and claimed.

In the accompanying drawings, Figure I is a view in side elevation ofsufficient of a loom to illustrate the application of my invention withmy invention applied thereto. Fig. 2is a sectional view of adetail. Fig.3 is a view,

crossing devices. Fig. 4 is an end view of a portion thereof. Fig. 5 isa view ofa portion of the pattern-roller. Figs. 6 and 7 are views of oneof the washers of the said pattern-roller. Fig. 8 is a view of one ofsaid washers with a number of the lugs hereinafter described appliedthereto. Figs. 9 and 10 are views of one of the said lugs. Figs. 11 and12 are views of one of the needles hereinafter described.

Mounted upon the arch B of the loom-frame B is a reed, N, having top andbottom or side bars, e e, and end pieces, a, to which the side bars areattached by means of screws 6 e or in any other convenient manner.

N are the dents of the reed. In practice these dents will be separatedand spaced by substantially the same means shown, described, and claimedin my application filed September 20, 1886, Serial No. 214,070.

Pivoted upon the upper side bar of the reed, at w w, are needles D, eachhaving an arrowshaped head, (1, which may be cast or constructed ofsheet metal, as desired, and a loop, d, of fine wire secured to saidhead, as shown.

P is the pattern-roller, the same being composed of a shaft or spindle,m, and a series of Patent No. 380,760, dated April 10, was.

varying widths,according to the desired spac ing. Between adjacentsleeves or washers m are placed small plates or lugs h, each having theouter projecting portion thereof bent or laterally deflected, as shown,the number of plates in the series between any two sleeves or washersvarying in the construction shown from 1 to 12. Any number of lugs maybe employed in each series,according to the diameter of thepattern-roller and the requirements of the pat-tern to be woven, and thesaid lugs may be placed at any desired points in the length of theroller. Part of the lugs are bent to the right and part are bent to theleft, either kind being employed, according to the direc- 6 tion inwhich it is desired that the needles should be vibrated. Each end of thespindle or shaft in is screw-threaded, and upon each end is a nut, 9,serving to firmly clamp together the sleeves or washers and the lugsintermediate the same. On one end of the said spindle or shaft is also aratchet-wheel, t, having teeth corresponding in number with the lugs inthe series around the roller, in the present case twelve.

Loosely mounted 011 the shaft or spindle in is an arm, R, on which ispivoted a pawl, H, drawn into engagement with wheel t by a spring, H. Arod, 0, having at its lower end a strap encircling the eccentric F uponthe crankshaft f, is pivoted at its upper end to the arm R and serves tocommunicate motion thereto from the said eccentric.

In operation a portion of warps are passed through the ordinary harnessX Y, which is situated behind reed N and between the dents N of reed N.Another portion of the threads is passed, either singly or in groups,through the half-heddles Z, then through the spaces between dents NQandthen through the loops 0 d. The crossing is effected by lowering theordinary harness-frame controlling the warps which are to be crossedaround the warps passed through the loops d. Then, while the loweredwarps remain below the ends of said loops at, imparting a partialrotation to the pattern-roller, so as to bring fresh lugs thereon intoengagement with the arrow-shaped heads of the needles and to vibratelthelatter from one side to the other of the lowered warps, and Ice thenraising the said lowered warps, the movement of the needles causing themto assume positions which permit them to deflect the rising threads tothe sides of the threads within loops d opposite those on which theywere before-that is, assuming the needles to have been moved in onedirection or the other by the action of the lugs on the pattern-roller.Heddles Z, which are constructed as halfheddles, for the sake ofconvenience, serve to raise the threads passing through loops (1, asrequired in the production of the pattern.

The arrangement of the lugs upon the pattern-roller is entirely inaccordance with the pattern to be produced. Avery great variety ofpatterns may be produced, inasmuch as every needle is independentlyacted upon by its series oflugs,and the latter may be arranged in anydesired manner around the patternroller.

Having described my invention, I claim-'- 1. The combination,with theshaft or spindle. m, sleeves or washers m", and nuts of the lugs h,having the laterally-deflected portions, substantially as described.

2. The combination, with the shaft or spindle m, sleeves or washers m,nuts 9, lugs h, having the laterally-deflected portions, and means forrotating said shaft or spindle, of the reed and needles pivoted theretoand constructed, as described, to be deflected by the engagementtherewith of the said lugs, substantially as described.

3. The combination, with the shaft orspindle m, sleeves or washers m,nuts 9, lugs h, having the laterally-deflected portions, and means forrotating said shaft or spindle, of the reed and needles D, pivotedthereto, substantially as described.

4. The needle D, having the arrow-shaped head, and the loops at of finewire fastened to said head, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
